CRM Migrations Without the Data Disasters
Data migration is the #1 reason CRM implementations fail. Industry research shows that 83% of data migration projects experience failures or delays, with the most common issues being incomplete source data discovery, poor field mapping, missing relationships, lost activity history, and inadequate validation. The downstream cost is far worse than the migration itself: lost pipeline visibility, broken integrations, and 6-18 months of CRM credibility damage with end users.
Widelly treats CRM data migration as a dedicated engineering discipline. not a side task during configuration. Our migration team has executed 200+ CRM data migrations across all major platforms, including multi-million-record enterprise migrations, multi-source consolidations, and M&A integrations. We commit to a zero-data-loss SLA, dual-run validation, and full reconciliation reporting.
